Current bearing has od of 69.012mm not including the shoulder This pdf download from Timken is poor on detail so will need to do som measuring for width ect. Just tryed contacting Mike Kurn who is out at the moment but hopefully will come back to me later today hoping he will have some ready maid salutions. Anouthe issue is the spindle threads where preload is applyed are not good any ideas if they can be re-cut or repaired in some way I was thinking something on the lines of a bush with new threads on outside smooth on inside and having spindle ground accordingly. This could affect my inner bearing diameter so need to consider this at same time. |

Hi Guys Thanks for your input. just wondering if i can get lathe to run with what I have got long enough to make a sleeve. If I want the bearing to be press fit and stay in sleeve how much smaller than the bearing should I make the sleeve and what would be most suitable material? |

yes its the fourth picture down . I think I might be tempted to make a pair of "Top Hat" adapter sleeves ... Same external dimension as the existing bearings, and bored [with a 'stop'] to take a conventional Taper Roller Beaing assembly ... Certainly worth checking what Bore and Outside Diameter combinations are available. Yes it is something I can consider. thing is the machining I would have to pay for so could end up costing as much as getting genuine parts its one of them times when if lathe worked could do it myself.

yes its the 4th and the 14th picture down. I also need the gear to the left of the pully on picture 14 note the locating squares are part of gear not part of pully. Edited By Ian Lunn 2 on 11/12/2014 21:54:50 |

Paul, I think he is referring to the fact that the outer race has a flange to locate it in the headstock casting. I guess you could try using a high strength retaining compound to fix the outer races in place but it may be safer to fix retaining collars to the headstock casting. Have a word with Mike Kurn (ex Acorn Machine Tool Co.) he used to, and may still, stock spares and is very helpful. I'll send you a PM with his telephone numbers. Thanks Russ if you could much appeciated.

Just restoring Acorn/ Halifax lathe and the taper bearing on the spindle is not good. The Price of these timken bearings is silly as could be into £300 for the pair (the lathe is only worth £250). Looks like its due to the outer part having a shoulder. I can get same bearing without a shoulder at much lower price. Is it done to just use inner section and rollers from new bearing with the old outer that has the shoulder. Also can the outer be reground? |
